Engaging in laboratory practical activities, developing laboratory practical skills, and, to a degree, even wearing laboratory protective equipment such as safety coats and goggles are all quintessential components of chemistry education. It is becoming quite common for institutions to invest in large-scale chemistry teaching laboratories, filling…

A quantitative titration of the amount of magnesium hydroxide in milk of magnesia using only items purchased in grocery and retail stores is reported. Either vinegar or a solution of food grade citric acid serves as the titrant, while food dyes advertised as being extracted from natural sources provide the end-point indicator. An inexpensive,…

Comprehensive curricula are described for middle and high school classrooms built around the synthesis of biodegradable calcium alginate capsules prepared from food-safe chemicals. Experiments and activities question whether calcium alginate capsules are a viable alternative to single-use water bottles and consider what characteristics are…

Exciting developments in the field of Green Chemistry spur the continuous innovation of experiments in the teaching laboratory. Beyond learning practical techniques, students can critically assess experiments using relevant metrics to propose further improvements and identify the most important interconnected impacts of these alternative products…

This paper examines the current state of the implementation of green chemistry into organic chemistry textbooks. Content analysis of the 15 most used organic chemistry textbooks revealed that only 10 of them had any mention of green chemistry. In textbooks that contained mentions of green chemistry, it was mentioned on less than 1% of pages. Green…

A laboratory experiment was developed to introduce students to waste valorization. This is the process of reusing, recycling, or composting from wastes, useful products, or sources of energy. In this laboratory experiment, waste valorization is demonstrated through transforming waste orange peel (WOP) into a marmalade-type gel by extracting a…

To date, the efficacy of virtual experiments is not well-understood. To better understand what differences may exist between a hands-on learning environment and a virtual learning environment, three experiments were chosen for investigation. For each experiment, approximately half of the students completed a hands-on version of the experiment, and…

This article examines the intersection of environmental justice and undergraduate chemistry education through a review of existing publications that highlight successful strategies for chemistry educators interested in incorporating environmental justice into their classrooms. It emphasizes the key roles of racial and social justice in the…

In recent years, immersive technology tools have burgeoned. After the release of the affordable Oculus Go headset and the Merge Cube, there has been increasing use of virtual, augmented, and extended reality (VR, AR, XR) in classrooms. Of significance to chemistry educators are the virtual lab simulations developed by Labster and HoloLab Champions…

This article aims to analyze the potential of new technologies in the area of green chemistry didactics. When viewed through the lens of systems thinking, the use of these ubiquitous tools can be a driving force for the development of a sustainable world because of their global use and reach. The authors concentrate on flat e-learning platforms,…

The COVID-19 pandemic resulted in implementation of a wide variety of technological tools to facilitate classroom instruction. However, the accelerated implementation timeline provided limited opportunities for evaluating the effectiveness of the various approaches. Here, we report on our use of three tools designed to enhance student…

To date, few general chemistry laboratory studies have included affective measures despite calls for more research on aspects of this domain. This shortage of studies may be partially due to the scarcity of affective measures that have been designed for, or tested in, the college laboratory setting. To provide measures for use in this environment,…

Copying adjacent answer sheets on the oft-used multiple-choice exams can be prevented if exam material is scrambled. The latter mode has been a requirement for all exams of this type at McGill University for 26 years. Cheating by copying has been reduced to nearly zero in this time. The experiment carried out used permissive seating and a single…

Experiential learning is a foundation in chemistry courses from the introductory-level course to upper-level courses through laboratory experiences. Service learning is another type of experiential learning that is slowly gaining momentum in the sciences. There have been several reports in this "Journal" on this pedagogy with respect to student…

Although ionic liquids have been investigated as solvents for many applications and are starting to be used in industrial processes, only a few lab experiments are available to introduce students to these materials. Ionic liquids have been discussed in the context of green chemistry, but few investigations have actually assessed the degree of…
